We stayed at the Decameron Boutique Los Delfines for two weeks in March 2017 and overall were mostly satisfied with this resort after a few initial problems. We had booked this hotel in August expressing our desire for an end room or upper floor room closer to the ocean since because I had been there previously I knew these were the largest and quietest rooms on the resort. When we arrived they gave us a lower floor room furthest away from the ocean and closest to the busy street that is right in front of the resort. It was very noisy into the wee hours of the morning and because the rooms are not soundproof we didn't sleep well. This was disappointing since it was the worst possible room and the last one that I wanted. After complaining to the front desk they gave us a room on the upper level but still next to the street and the noise kept us up half the night again. Again I firmly requested a room away from the street so they finally gave us one on the lower level far from the street and this was much better although we could still hear the people directly above us. They might as well have been standing next to us that's how loud it was but we settled in and made the best of it for the remainder of our vacation and slept quite well. We eventually found out that the Decameron resorts had been sold to a new owner and the upper floor rooms were now junior suites for families, and couples had to take the lower units. I did see only couples in some of the upper floor rooms so I'm not sure that reason was really valid. Despite these initial problems I will list the pros and cons of this resort. Pros - very clean resort - a la carte restaurant has the best food of all the Decameron resorts in San Andres -friendly restaurant and bar staff -location - the main beach is only steps from the resort, shopping right outside the resort, five minute walk to the Decameron Aquarium for excursion bookings. - quick restaurant reservations to any of the other Decameron resorts. - small resort, 36 rooms, lounge chairs and umbrella right outside our room, quiet during the day and evening. Cons - unfriendly front desk staff. made us feel unwelcome and we felt like we were an inconvenience - language barrier may have been a factor but don't think so. One girl, Angie was very nice. - rooms - paper thin walls so you hear every noise unless your on the upper floor away from the street. - advertised as an adults only resort but families and children were there. - only one other English speaking couple but mostly Colombians who are lovely people by the way. If we could have gotten the room we had requested it would have been an even more enjoyable vacation but it was still a fantastic holiday and we enjoyed beautiful San Andres Island. So much to do and see here. I would go again and would stay at the Los Delfines if we got our requested room. All the other Decameron resorts on the island have there pros and cons but they are all nice nonetheless.
